Many times I was faced with a question - what is the best way to model data processing pipelines in Java for the very common "small/medium data" workloads. In traditional data analytics (Python/R) and Big Data (Spark) the answer is a structure called DataFrame - a dynamic 2D table with a lot of query and transform operations. But why is there no DataFrame in Java?

DFLib (https://dflib.org) is the library intended to fill this gap. It sits somewhere between ORM and Big Data solutions. This particular presentation is pretty old and talks about a very early version of DFLib. You should probably check newer talks by Andrus Adamchik on the same topic by. E.g. this one given in JUG Milano in 2024:    • DataFrame - a Swiss Army Knife of Java Dat...
